After further testing, I RELEASE loBo, then I try to open the parent class of the class I tested so I can edit it, but it says: "Remove classes from memory?" and I click "Remove", then it says "Cannot modify a class that is in use".

So I know that when I click "Remove" that each time it is killing an object reference, and eventually, every thing get released and it will finally open it. I'm sure it a case of there still being object references hanging around in the class I created, and I will find and fix that issue...

>However, I wondering how I can determine, from the VFP IDE, what all variables or objects references are hanging around in the VFP environment. Surely there is a way to see what object references are alive in VFP at any given time. This would help me spot where the problem is, rather than me having to dig all around in my code trying to spot the problem.

You can do DISPLAY MEMORY to see the status of memory variables.
